A. GOLTON, OF LE ROY, NEv YORK.

VALVE-PROPELLER.

Specification of Letters Patent No. 20,382, dated May 25, 1858.

To all wlw/m it may concern;

Be it known that l, Anon Confront, of the town of Le Roy, in the county of Genesee and :State of N ew York, ha\'e invented certain new and useful Improvements in Propellers; and I do hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the annexed drawings, making' a part of this specification, in which-M Figure l, represents a vertical longitudinal section of niy iniprmeinents, F ig. 2, indicating the plane of section. Fig. 2, is a plan or top iew of the saine and, Fig. 3, is a transverse, yer-tical section of one of the sliding fraines, y, y, Fig. indicating the plane of section.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to paddles placed in horizontal sliding frames and it consists in attaching the saine by means of pivots, between their centers and their upper edges to these frames, the upper edges being guided by loops, which are attached to horizontal plates which are placedon the top of the sliding franies in such a manner that they assunie a separate sliding inotion, independent froin the inotion of the frames, whereby the paddles are inclined either one way or the other, and it further consists, in a peculiar arrangement of stops, which are'so constructed, that by placing the saine either on one side of the paddles or on the other the latter are inade to propel the Vessel forward or backward, and that by releasing the stops altogether the paddles inove both ways with the sliding frames without any effect in propelling the Vessel either in one direction or the other.

To enable others skilled in the art to fully understand and construct iny improvements I will proceed to describe the saine.

A, is a fraine work which forms the support for two or incre pairs of horizontal ways B, and which is supposed to be attached to the stern of a vessel. The ways B, forni the guides for the sliding frames C, C', in which the paddles D, are arranged, each frame carrying Q or more paddles. Plates E. are placed loosely on the top of the fran'les C. C, being held in their position by the rods d, which forni a staple on each side of the frame for the plates to pass through; and loops are rigidly attached to the under sides of these plates, at suitable distances. The paddles are attached to the sides of the fralne C, by ineans of pivots o, which are fastened to the paddles about inidway between their centers and their upper edges, and openings d, are cut in the iniddie of the paddles from the upper edges down to soine distance to inake rooin for the loops b. Rods e, which are rigidly attached to the upper edges of the paddles, pass loosely through the loops Z).

Ears j, are provided on the upper sides of the plates E, to which connection rods F, are attached, which extend to a crank shaft G. Two cranks G, G2, are provided on this shaft in opposite directions so that the sliding frames assume a reciprocal inot-ion. Horizontal rods g, are attached to each .side of the frames C, having their bearings in projections L, which are rigidly fastened to the sides of the frames, and the hooks z', extend from said rods downward, the hooks being placed at such distances on the rods g, that they correspond to the position of the paddles, and these hooks extend through the sides of the frames C, as clearly shown in F 3, and forni the stops of the paddles D. Small springs j, keep these stops in their position. Short arms 7.1, extend from the rods g, in a horizontal direction and rods Z, are provided which extend from one end of the ways B, to the other, haying their bearings in the ears Z. The ends of these rods, which are nearest to the vessel, are bent up "ard, forming the loops m, and those parts of said rods which run alongside and under the ways B, are bent so as to forin a sort of cranks, extending from one end of the ways B, to the other. The arms 7J, extending from the rods g, rest on the rods Z, and a string n, is att-ached to the loops z', which inay be extended to the inside of the Vessel.

The operation is as follows The crank shaft G, is turned so that the sliding fraines C, C, are inovcd in the direction of the arrows. The paddles D, attached to the frame C, which moves in the direction of arrow l are arrestedV in a Vertical position by the stops e', and they will therefore, by coining in contact with the water (as shown in Fig. l) propel the vessel in the direction of arrow 3. At the saine time the sliding frame C', moves in the direction of arrow 2, and the paddles attached to this fraine being released by the stops z', are left free to be inclined as shown in Figs. l and 2. The paddles are inclined by the action of the plates E, for whenever a strain is exerted on these plates which tends to move the same in a horizontal direction, the loops Z), will bear against the rods e, on the upper edges of the paddles D, and have a tendency to turn the same on the pivots c. The paddles D, there- Jfore will be inclined either one way or the other according to the action of the cranks Gr, G2, on the plates E, unless prevented from being inclined by the stops z'. It is obvious for this reason that by releasing the stops z', the paddles are inclined in going backward as well as in going forward and. they will not have any effect in propelling the vessel. If however the stops z', are put on the outside of the paddles (away from the vessel) the latter will be arrested in a vertical position while moving in the direction of arrow 4, and the motion of the vessel will be retarded or the vessel will be propelled backward.

The stops z', are operated by the rods Z; by pulling the string n, the loops m, are turned down, whereby the crank parts of the rods Z, are turned up to a position shown in red outlines (Fig. and the stops z', are pulled back. As soon as the string a, is released the stops z', drop into their places by the action of the springs j.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is, Y

The connection of the paddles with the sliding frames C, C, and the fiat plates E,

in combination with the stops z', constructed and operated substantially as described.
